Chan-Vese Model with Semi-Implicite AOS Scheme for Images Segmentation: Biphase and Multiphase Cases

Active contour models are designed to evolve an initial curve, called level set, to extract the desired object(s) in an image. Various models are used, such as Chan-Vese (CV) model. The CV model has the global segmentation property to segment all objects in an image. The problem with this model is the high time computing. In order to reduce it, our contribution in this work is the association of a semi-implicit Additive Operator Splitting (AOS) technique with the CV model in biphase and multiphase cases. In this paper, we present the new association in biphase and multiphase cases with simulations showing the efficiency of the proposed method.
